Encore combined with Shadow Tag,  allows Wobbuffet to either give a free turn to a setup sweeper or remove a counter, guarenteed. Custap Berry is what makes Wobbuffet mostly useful, if anything your statement contradicts itself. I do agree that its specific niche is to beat out specific counters mainly due to its ability and movepool, the only item that it can run now is Leftovers which does give it survivability but in most cases it's going to be 2HKO'd as it can't risk constantly switching in, then encore(it's not very fast too). And that's all it can ever run anyway, so any set-up sweeper would be sure play mindgames with it by attacking or setting-up.
